The Gaia mission and science highlights from the Gaia data releases
Anthony Brown
Leiden Observatory
The European Space Agency's Gaia space mission, launched in 2013 and expected to operate through 2022, is designed to measure the brightnesses, colors, positions, distances, and motions (in three dimensions) of almost two billion of the Milky Way's hundred billion stars. These measurements are yielding new insights about the internal structure and formation history of the Milky Way, thanks in part to a series of increasingly comprehensive data releases that any member of the astronomical community can access. In this talk, I will introduce the Gaia mission and briefly summarize the latest data release, Gaia EDR3. This discussion will be complemented by highlights of the science results from Gaia DR2 and Gaia EDR3, showcasing among others the impact of Gaia on solar system studies, the Milky Way's accretion and recent dynamical histories, and understanding matter in extreme states.
Anthony Brown is associate professor at Leiden Observatory and has been involved in the ESA Gaia mission since 1997. He currently chairs the Gaia Data Processing and Analysis Consortium, a team of over 400 European astronomers and IT specialists who are in charge of turning the raw measurements from the Gaia spacecraft into the Gaia data releases. Anthony is very broadly interested in the astronomical research that can be done with the aid of Gaia data, from studies of our own solar system to understanding the formation history of the Milky Way.
